Figure 5From: PKDGRAV3: beyond trillion particle cosmological simulations for the next era of galaxy surveys Weak and strong scaling. Perfect \(\mathcal{O}(N)\) scaling should follow the slope of the ‘perfect scaling’ line. PKDGRAV3 exhibits perfect weak scaling and excellent strong scaling out to 300 times the number of nodes. This translates into node memory usage starting at 30 GB and scaling to 0.1 GB.Back to article page
